The Design And Implementation Of User Interests Analysis System BackGround In SAP Corporation

With the development of the of information industry and the Internet,the information exchange has mainly from the PC end to the mobile end.The amount of information has become larger and larger in the mobile end,and this information is produced by persons’ work、live and social activity. It is the reflection of the thought, mentality, interests and value etc. Therefore, whether you can obtain and extract the valuable information through data mining for scientific research or commercial has grow into a hotspot. When I am a intern in the SAP, involved in the design and implementation of such a type of project-User Interests Analysis System.User Interests Analysis System is a web application based on data visualization and LBS. It mainly describes that extract the feature words from the web text from URLS and then statistics, analysis and display them. The paper introduces some techniques for this System. For example, web spider technology to obtain the HTML structure and text. OpenStreetMap provides open source map service. Followed by the analysis of user needs and combined it with technology to totally design the whole System and specific design to each module. Finally, this article exposits the implementations of part modules and map server of User Interests Analysis System.In implementation of users Interests, mainly we describe the parse of HTML structure and based on TFIDF algorithm in obotaining the user Interests. In check user interests modules, we mainly describe the implementation of data access service class and the interface of business logic function and its corresponding DAO class, and the draw of heatmap. In Search module, describes the implementation of its associated function with the frontend interface. Finally, it describes the building、configuration and invoke of the OpenStreetMap.
